    Default Connector question

    I have been trying to figure out my harnesses, I have an 86 main harness but I have an 90 ecu harness to convert to mass air. (The harnesses were hacked out when I found it) but now im onto the ecu area. What are these 2 connectors? the round grey and the green? what do they connect to? and I think the brown one behind is the ecu relay? Attachment 126749

    The relay is for the ECU. The green plug is most likely the instrument panel gauge wires. There should be matching plugs in the kick panel to plug them into. Should be two 8 pin and a mate to the round one. The 86' cars had the fuel pump relay under the drivers seat. The round one may go to it.

    I tried using the EVTM. I can give you possible connector numbers, but since we don't even know what system they are for, it's like a needle in a haystack. I even tried looking at all the connectors in the connector index that should be green, and, at least for '88, it doesn't show one in the passenger footwell.

    I have checked the other connectors wires on this ECU harness, and it is an 1990 harness, but cant find anything that tells me what these 2 are and where they go to.

    ok just dropped off my complete harness off to get them all talking to each other, I found out that the grey round connector is for the air bags... any connector e that has 2 wires twisted together is for the airbags

    Near the opposite end does that harness have a round gray connector and round black connector, or does it have a single round reddish/brownish connector?
    Gray and black = 1990
    Reddish brownish = 1991/1992.5
